Good point and definitely worth remembering.
But we're talking about simple box shapes with some text floating above.

I am sure there are no knock outs if you look at your file in XaraXtreme under overprinted black text.
Though I cannot check this myself, I don't believe that my printer is making these knock-outs up. So I am inclined to believe that Xara - despite object options "Overprint Fill" - exported the PDF/X with knock-outs.

I just moved the black texts to a new layer and will be sending off a new PDF to the printer's. Hopefully more news tomorrow.
